Answer:
6 * 3/4 = 9 2 = 412 = 4.5
Step-by-ste
6 * 3/4 = 6/1 3*4 = 18/4 = 9/2
2 · 2 = 9/2
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(18, 4) = 2. In the next intermediate step cancelling by a common factor of 2 gives 9
2
.
In words - six multiplied by three quarters = nine halfs.
M+B=640
M=3B
----------------------------------------------
Therefore:
3B+B=640
4B=640
B=640/4=160
----------------------------------------------
M+160=640
M=640-160=480
Therefore, Mike had sold 480 cars.
When a problem says that the price was increased by 100% + n%, it means you add on n% percent of the original price. In this problem, the original price was $35. The new price is 115% percent of the original price. So all we need to do is find 15% of the original price and add it onto the original price to find the new price.
$35 * 0.15 = $5.25
$35 + $5.25 = $40.25
The new price of the shoes is $40.25.
